IMPRovBD MEAT-GUTTER.

TO ALL WHOM IT MAY CONGERN:

Be it known that I, FRANZ G. SIEMERS, of, Winona, inthe county of Winona, and State of Minnesota: have invented certain new and useful Improvements in Meat-0hppers; and I do hereby declare that the fol' lowing is a full, clear, and exact `description thereof, reference being had tothe accompanyingdrawings, making part of this specification, and to the letters ot'- reference marked thereon, like letters indicating like`parts wherever they occur. v i

To enable others skilled in the art to construct and use my invention, I will proceed'to describe it.

My invention relates to meat-choppers, consists in the construction and arrangement of certain mechanical devices in a novel manner, so as to produce a new and useful machine for expeditiously cutting or chopping up meat. A

In the drawings- Figure 1 is a top plan view, with a portion broken away.

Figure 2 is a side elevation, and y `Figure 3 is a front viewA of thecutting-apparatus detached.

In constructing my machine, I make a suitable frame, consisting principally'of'thc uprights A. and B and the tables C and D, as shown in figs. 1 and 2. On the upper rear side of the uprights A, I mount a shaft, 4E,

' in bearings a, and provide it at one end with a crank, b, and at the other with a driving-wheel, F. In-front of thezruprights B, and near the lower table, D, I-mount a shaft, G, in bear-ings suitablefor the purpose, attached ytothe-uprights; and on one end of the shaft Gr, I attach rigidly a cranl -wheel-, I, and to the other a pulley- A'whez :l,c, and ily-wheel Il,'the former connecting with the driving-wheel F bythe belt or cord e, all as clearly shown in Iig. 1. y

` Tothe ily-wheel I-I and'wheel I,at points .equally distant from the centres, and in the same direction from t-hc same, I attach the pitmenfg,.and connect them to thc crossbar i, to which are rigidly connected the vertical hars i', which -movein guidesj attached to the uprights B, as clearly shown in figs. 2 andnS.

The cross-.har z, I provide with two or more vertical rods, J, arranged so as to be adjustable vertically by means of the nuts c, and having attached to their lower en'ds twoknives, l, respectively, shaped and arranged as shown iu figs. and 3. v A y v- A On the lower table, D, and immediately over' the shaft Gr, I mount a ,circular chopping-block, K, on a central pivot, m, shown by the dotted lines in iig. 1, and so as to run on friction-rollers liz, as shown in fig. 2.v This chopping-bloclt K, I construct ofseveral pieces, arrangedsoas to'present theinend's to the knives, as shown in lig. 1, unitingrand binding them together by .hands o, provided with set-serews 25,' so as to avoid splitting, and

to adjust for shrinking. If the parts composing the block become loosened from any cause, they can readily be tightened hy the bands and set-screivs.

On the under side of the chopping-bloeit, I fasten a` ratchet-circle, L, so as -to project beyond theouter edge ofthe block, as shown in g.`1; and on the table D, just in front ofthe shaft G, I mount a short rook-shaft, q, provided with two arms, r and s, as shown in figs, 1 and 2.` To the end of the arm s, I hinge a pawl, t, which operates against the teeth of the ratchet-circle L, an'd turns the chopping-block. The armr passes immediately under the shaft G, and is held up oy a spring, u, attached to the side of the table D. On the shat'tjG, I place an eccentric, z', which, in revolving with the shaft, presses down the arm r, which, in turn, causes thepawl t to turn the chopping-block. Nour the other side of the chopping-hlock, and to the u'pright, B,I attach a pawl, w, for holdin the block K in position as it is moved. The upper side of the chopping-block, I provide with a removablecu'rb, M, as shown in iig. 2, within which the meat to be chopped is placed.

To each of the bars J, two knives are generally attached, as shown in lig. 2. When two bars are used, and two knives attached to each, and arranged to work on the chopping-block, as shown, the meat will be cut quicker and tncr at. thecentre of' the blockthan out near its periphery'.y In order, however, that the meat may be.

thrown vto the centre, so as to be cut evenly, I attach to the rcarside of the cross-pieces uniting the uprights B, a bar, N, so as to be adjustable vertically` by means ofthe set-screw O, and having connected to its lower end a scoop or scraper, P, shaped so, as to force themeat from the edge of the block to its centre.

In operating my machine, I first prepare the meat on the table C,and then place ition the chopping-block K within the curb M; and then, adjusting the knives Z andseraper ,P as desired, I turn the crank '5, which revolves the driving-wheel F, and by meansof the belt e, the wheel c and shaft G. The shaft G revolves the wheels I and H, which, by means of the pitmenf and g, give la reciprocating vertical Vmotion to the knives Z. At the same time,.by means of the eccentric, v, it operates the rock-shaft q and turns the chopping-block K. These movements are so timed that when the knives descend, the block K is stationary, and as Vthey ascend, it is turned the distance of one tooth of the ratchet-circle; and as the block is stationary when the knives strike it, but little injury is done, either to the knives or the table or block. As the block `revolves, the shape of the vscraper P will constantly force the meat `from the outer edge to th centre, and thus the mcatlwill be cut uniformly., l l

As avery rapid motion can be given to the knives, it is obvious that the chopping can be done thoroughly and quickly. v

I When the rst lot is chopped, it can be removed and placed upon the lower table, D, and a new lot put on the block, and cut up as before. For convenience in removing 4the meat from the chopping-block, I make the curb M so that it .can be readily slipped on or off the head of the block.A Besides, by having it removable, thc head of the block can at any timebc.cleaned or a new piece inserted.

Having thus described my invention, what I claim, is l. The meat-'cutting machine, consisting of the frame'A B, with the tables C D, the reciprocating frame li, with the seriesof 'knives attached thereto, andthe rotating chopping-block K operated by the shaft G, the

rocleshaft g, and pawls tfand w, all constructed and arranged to operate substantially as herein described.

2. The chopping-block K, consisting of a series of pieces set endwise and bound together with band o and set-screws p, and provided with the removable curb M, constructed and arranged as herein described. l

3. The arrangement of the tables C `-D, in combination with the meat-cutting apparatus, when constructed as herein set forth. v l
